NQ Air Purification Systems

Proven & Patented Technologies


High Efficiency 99.99% HEPA + Ultraviolet Germicidal Irradiation + NQ Industries has designed a range of patented, high-quality products, utilizing a combination of well-recognized technologies with proven efficacy, including Ultraviolet (UVGI), HEPA Filtration, Activated Carbon Filtration, and Ultraviolet Photo Catalytic Oxidation (UVPCO). These technologies have been proven to deliver the purest, safest air for indoor environments.

HEPA Filtration

HEPA filters are well recognized and are an efficient way of filtering microorganisms bigger than 0,3 μm. HEPA filtration can be effective, but their fragile materials and lifespan why NQ systems also utilize Ultraviolet Germicidal Irradiation (UVGI) as an extra security and safety measure to offer increased protection.

Testing and quality information

  • All “certified” HEPA filters have been tested using the D.O.P. method
  • The DOP test procedure can evaluate particle penetration and airflow resistance properties of a variety of filtration materials (e.g., HEPA filters, NIOSH respirators, and filter media). The procedure employs a cold aerosol of dioctyl phthalate (DOP) or Emery 3004 oil using a TSI® CERTITEST® Model 8130 Automated Filter Tester. Test articles are challenged with particles of the most penetrating particle size range, i.e., 0.3 µm. Filtration efficiency measurements can be determined up to 99.999%. Samples can be tested at flow rates up to 90 L/min
  • All HEPA filters will bear a certification label to ensure that the filter is a “true” HEPA filter. Imitations in the medical field do not count!
  • Hospitals require testing information to be affixed somewhere on the filter
  • ASME AG-1 “Code on Nuclear Air and Gas Treatment” is the new standard by which the filters are tested worldwide

0.3 µm. Filtration efficiency measurements can be determined up to 99.999%

UVGI (Ultraviolet) Lamps

UVC radiation at 254nm has an intense germicidal effect. UVGI alters the pathogen’s DNA/RNA, inhibiting its ability to replicate. Micro-organisms, such as viruses, bacteria, fungi and yeasts are effectively deactivated without the addition of chemicals within seconds.

Benefits of using UVGI UV (Ultraviolet) Lamps technologies

  • Micro-organisms can’t replicate due to a single pass kill
  • At a sufficiently high intensity, UV disinfection is a reliable, simple and fast method to sanitize the air
  • Internal arrangement of the systems sanitized (single pass) No living organisms left in filters

Safer maintenance

  • Micro-organisms smaller than 0.3 micron are inactivated and makes the NQ systems safer than simple HEPA air purification systems
  • Ozone free lamps, high-efficiency, no leaks
  • UV Dosages needed for inactivation are defined upon UV Intensity and the time the microorganisms will pass through the UV killing zone to be inactivated.

Activated Carbon Filtration

Almost all odors are connected with gases. Even HEPA filters have almost no ability to remove them from the air. The best solution to odor control uses a combination of adsorption and oxidation.

How Activated Carbon Filtration Works:

  • In adsorption, most commonly using activated carbon, gas molecules wind up attached to the surface of the collection medium. Think of each granule of activated carbon as a golf ball with many microscopic dimples. The gas molecules fit into the dimples and are held there by molecular forces.
  • The effectiveness of the adsorption process is affected by the amount of time that the stream takes to pass through the filter (residence time) as well as the density of carbon. When all the dimples are filled, the carbon is saturated and will begin to pass odors through and need replacement. Therefore, the more carbon in the filter, the longer it will last.
  • Some odor-causing molecules will not adhere readily to the surface of the carbon. Fortunately, a process called oxidation in which oxygen is added to the gas can chemically transform most of these molecules.

The result is an air stream that no longer has odor problems.

Photocatalysis – UVPCO

The studies on the air cleaning technology by Ultraviolet Photocatalytic Oxidation (UVPCO) have shown its capacity to completely oxidize a broad range of organic compounds at ambient temperature. UVPCO can successfully be applied in the buildings to reduce concentrations of Volatile Organic Compounds (VOCs), as well as a broad panel of airborne pollutants.

How UVPCO Works

  • The process lies in the use of titanium dioxide (TiO2), which reacts with UV light (UVC at 253.7 nm). This interaction, in complement of air and water vapors, will create hydroxyl free radicals, which will generate oxidation of organic materials to destroy.
  • Unlike conventional powder TiO2 treatments, NQ Industries has utilized a cutting-edge technology using TiO2 on a molecular level, which eases the installation and maintenance of the TiO2 compound, and thereby extending its deployment life by a factor of 4 above any other type of compound in the market today!
  • This process has been used successfully for several years for cleaning surfaces such as historic buildings, panes or frontages of buildings

NQ Industries Inc. introduced this cutting-edge technology in 2006 in order to increase the efficacies of NQ systems upon certain VOCs, odors or chemical pollutants that have to be treated.

ACH Calculator

Accurately calculate required Air Changes per Hour (ACH) for 99.9% removal of airborne contaminants based on environment size and application.

  • Isolation wards = 12+ ACH\
  • Food industry = 6 to 8 ACH
  • People having allergies = 6 ACH
  • Smoking environment = 6 ACH
  • Standard space comfort = 3 ACH

Define the size of the room to treat in mÑ.

Having defined the number of ACH required and the size of the room to treat, you then determine the total Air volume (mÑ/h) needed

Define the number of NQ Air Purification Systems required

Pathogen Size Facts

Pathogens, including SARS, Coronavirus/COVID-19, are around 0.1 microns in size

Standard HEPA is 99.97% efficient @ 0.3 micron not 0.1 micron

Most of the pathogens will not be trapped by the filter but pass through

The smaller the pathogen, the easier it is to be deactivated by UVGI

Which is why NQ Air Purification Systems are built with both

Safer + Easier Maintenance

Example of maintenance for an NQ500 installed in an isolation ward. The maintenance required would be as follows


Pre-filters to be changed every 3 months (for pre-filter No1) and 6 months (for pre-filter No2)


UVGI lamps to be changed every 10,000 hours


HEPA filter to be changed every 18 months

For each new patient in this room, the inside of the machine will not have to be cleaned. The outside of the unit will only have to be sanitized (along with the rest of the room)

Also, please note that NQ used filters are not considered as biohazardous waste
